Is there a sound that cancels noise?
A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) relative to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out – an effect which is called destructive interference.

What is the difference between noise-cancelling and noise reduction?
Passive noise cancellation can lessen mid to high-frequency noises by about 15dB to 30dB. Noise-canceling headphones, on the other hand, make use of electronics that send out sound waves to nullify the ones coming from the environment.
